1、　　課 時 作 業(yè)　 31 Ⅰ.閱讀理解 (2019·綏德中學(xué)高三階段性測試) Are you sick of going to bed late and waking up tired? Then grab your hiking boots and a tent. A new study suggests that camping in the great outdoors for a couple of days can reset your body clock and help you get more sleep. The body clock is an internal

2、 system that tells our bodies when it's time to go to sleep and when it's time to wake up. Scientists track this clock by measuring the amount of melatonin (褪黑激素) circulating in a person's blood at any given time. In a healthy sleeper, melatonin levels rise a few hours before bedtime, stay high thr

3、ough the night, and then settle back down when it's time to wake up. In our modern society, however, most of us stay up many hours past sunset and would probably sleep in many hours after sunrise if we could. And the trouble is, your melatonin levels may still be high when your alarm clock goes off

4、 in the morning, which leads to fatigue. It may also have other health consequences as well, such as diabetes(糖尿病), overweight and heart disease. Professor Kenneth Wright of the University of Colorado in the US wanted to see if our body clocks can be reset by a short stay in nature. His team recrui

5、ted(招募)fourteen physically active volunteers in their 20s and 30s. Nine went on a weekend camping trip, while the other five stayed home. At the end of the weekend, the researchers reported that in just two days, the campers' body clocks had shifted so that their melatonin levels began to rise more

6、than an hour earlier than they did before they left on the trip. By contrast, the body clocks of the group that stayed home shifted even later over the course of the weekend. “This tells us we can reset our clocks fast，”Wright said. Therefore, if you want to change your sleep patterns you could tr

7、y to increase your exposure to natural light during the day and decrease the amount of artificial light you see at night. And if that doesn't work, there's always camping. 本文為說明文。生物鐘對人體的影響很大。生物鐘如遭到破壞，可能會影響人的健康，如患糖尿病，身體肥胖，心臟病，尤其是影響我們的睡眠。一項新研究稱幾天的戶外露營便可以重啟你的生物鐘，幫助你改善睡眠。 1．What is the author's main p

8、urpose of writing the passage? A．To explain how a lack of sleep is bad for our health. B．To inform us of a possible way to adjust the body clock. C．To analyze how the body clock influences our sleeping habits. D．To explore how the body clock is connected with melatonin levels. 答案：B 解析：推理判斷題。第一

9、段中的A new study suggests that camping in the great outdoors for a couple of days can reset your body clock and help you get more sleep. 一項新的研究表明，在戶外露營幾天可以重置你的生物鐘，幫助你獲得更多的睡眠。及最后一段Therefore，if you want to change your sleep patterns you could try to increase your exposure to natural light during the day

10、 and decrease the amount of artificial light you see at night. And if that doesn't work，there's always camping. 因此，如果你想改變你的睡眠模式，你可以試著增加白天暴露在自然光下的量，減少晚上看到的燈光的量。如果這不起作用，還可以露營。由此可知這是告訴我們一種調(diào)節(jié)人的生物鐘的方法。B正確。 2．The underlined word “fatigue” in Paragraph 4 probably means“________”． A．tiredness B．excitement

11、 C．refreshment D．pressure 答案：A 解析：猜測詞義題。結(jié)合第四段中的your melatonin levels may still be high when your alarm clock goes off in the morning 早上鬧鐘響起的時候，體內(nèi)的褪黑激素還依然保持較高水平，因此就會使人感到勞累?？芍癴atigue”指的是疲勞的。A正確。 3．What did Wright's team discover from their experiment? A．The body clocks of the two groups didn't s

12、how much difference. B．The body clocks of those who stayed at home remained the same. C．Those staying outdoors reset the clock inside their bodies over a short period. D．Changes to the body clock don't necessarily affect melatonin levels in our bodies. 答案：C 解析：細(xì)節(jié)理解題。根據(jù)五段中的At the end of the week

13、end，the researchers reported that in just two days，the campers' body clocks had shifted so that their melatonin levels began to rise more than an hour earlier than they did before they left on the trip. By contrast，the body clocks of the group that stayed home shifted even later over the course of t

14、he weekend. 周末結(jié)束時，研究人員報告說，僅僅兩天內(nèi)，露營者的生物鐘就改變了，褪黑激素水平比他們出門旅行前提前了一個多小時開始上升。由此可判斷出Wright的團(tuán)隊經(jīng)過對比兩組人群的睡眠表現(xiàn)發(fā)現(xiàn)，我們可以在短時間內(nèi)調(diào)整生物鐘。故選C項。 4．According to the passage, to change our sleeping habit, we'd better ________. A．set an alarm clock to wake us up on time in the morning B．try to reduce melatonin levels as

15、much as possible at night C．spend several weeks staying in the open air every now and then D．get exposed to more natural light in the day but less artificial light at night 答案：D 解析：細(xì)節(jié)理解題。根據(jù)最后一段if you want to change your sleep patterns you could try to increase your exposure to natural light duri

16、ng the day and decrease the amount of artificial light you see at night.得知，白天暴露在自然光下，晚上減少可見的人造光線，就可以改善我們的睡眠習(xí)慣。D項符合題意。 Ⅱ.完形填空 (2019·新余四中高三段考) An American businessman who travelled in southern Mexico met with one young Mexican fisherman rowing a small boat at the dock (碼頭)． Inside the boat were se
